In non-LOS, mobile (mobile) is not what we usually think of as mobile. WiMax mobility is more like setting up a makeshift store while traveling, completing a task, packing up and moving on. Some service providers use this technology to provide end-user access in lieu of DSL or cable modems. The signal range in this non-line-of-sight scenario is about 3 to 4 miles, with a claimed data rate of 30Mbit/s, but you can lower that expectation to closer to 15Mbit/soOther service providers are targeting business users in fixed LOSWiMax deployments, where the topology is very similar to traditional T1, a point-to-point type topology with backhaul or backbone services. This fixed LOS claims to provide 30.70Mbit/s of throughput, but one can expect it to be about 40Mbit/soNote: I know of a company in the Seattle area that claims to be able to provide 10OMbit/s of point-to-point connectivity with 10Gbit/s of bandwidth per month at no additional cost. If you go over the 10Gbit/s limit, you pay extra.As an IEEE standardized WiMax technology, it has evolved from the original 802.16 to 802.16a, c, d, and finally 802.16eoAs mentioned earlier, WiMax defines the "last mile" of access. Figure 8-6 shows an example topology where a user has a point-to-point connection to a service provider and access to the public Internet 0 from the service provider.UserFigure 8-6 WiMax DeploymentWiMax operates in the 10.66 GHz band, so it does not interfere with 802.11 LAN, so why discuss this in this section? The idea here is that due to some planning, a device deployed as a gateway uses 802.16 "last mile" access or uplink access to a service provider to provide access to the 802.11LAN. From there.104 Chapter 8 Other Wireless Technologies
